With'm a casing W in. the Well known manner, suitable provision being rnade by means of a universal joint X or otherwise to provide i a free angular adjustment between the. pf E and V of the driven shaft and all the e3;- posed portions of the driven shaft may be inclosed in an outer jecket all of which is Well understood and need not be further de scribed.

My construction of drive mechanism presents many advantages. lt places the parts whichneed frequent attention in accessible positions from above, these parts being' all under the hood on the forward part oi the vehicle frame With ample space to all theA arts and leaving the space oelow the body tree and clear. The friction disk bearing as it does with its Weight u on the friction pulley is in the most Nlavora 'le position 'lior l'rictional transmission o'l power, besides it nrevents the settlement of any oil, Water or dust thereon which are the Worst foes ol fric-tional transmission.

F rom a constructive point of view the advantage of disposing the Whole driving mechanism including the engine in the longitudinal center oi the frame is Well understood and this arrangement obviously presents the most favorable'conditions for carrying the load under all conditions of running.

The upright position of the crank si engine or motor available for my purnose; e double o posed gasol'ene motor is novi/ever the one prefer to adapt for the construction of a simple compact and moderately priced motor vehicle of the runabout type.

The upright position of the rank snai-'t enn ables me also to apply a very simple and con venient startino mechanism by means of a .starting shalt "i located belovv'the hood directly in front of the drivers seat and operating throu h bevel gear connections with the up er en of the crank shaft.

7l,That l claim as my invention is 1. ln a motor vehicle driving mechanisn the combination of a drive shalt actuated by the motor and sup orted in vertical bearings, a iction disk at te lower end of said shaft, a longitudinally disposed driven shaft below the drive shaft, positive drive connection between tlie rear end of said shalt and the rear axle, a frame in which e portion of said shaft below the-friction disk is jonrnaled, a friction pulley shiftable upon said portion olf the sha'it and adapted to rotate the saine and means for raising and lowering tne frame.

2. In a motor vehicle driving mechanism, the combination of a drive shalt supported in vertical bearings on the forward part of the vehicle frame and constituting the main shaft of the motor, a friction disk carried on the lower end oi said drive shaft, a driven shaft extending longitudinally of the vehicle disk in verticalplene with the ..rive mit and vertically movable trom and tov/'ar .l t 1e friction disk, and friction pulley snplinednL on tbe driven shalt and endif-rise movable *i re 3. -..i motor vehicle drivin; mechanism, the coinoinat n with the vehice frame, or" a tor carried woon the forward of the drive shan, disposed L a 'lr ction pulley splined on said J`t and ada'eten to veriably Contact Ariction diei/i. v s rnc-tor vehicle driving mechanism, a rr o skdriven by the motor and ro tating in vertical bearings upon tire ortvard end oi' the vehicle trarne-,- a driven shalt err-- tendrng longitudinally ci the traine below the l drive shalt to the axle and in positive driving connection therewith and a friction pulley 'l'tably snlined upon the portion oi s 1 seid shalt ed to contact the tace thereof.

8. ln a niotor vehicle driving mechanism thereon within the casing across the face of the friction disk, afoot' le \'erha\'n1g aetuatthe combination with the vehicle frame, of a ,drive shaft supported in vertical bearings, a

'driven shaft journaled in said casing longitudinally of the vehicle frame, and a friction pulley splined upon the driven shaft and 1 shiftable within'the casing in contact with i the friction disk.

tt .ln a motor vehicle driving mechanism, the combination with tlicivehicle frame, of a drive shaft supported in vertical bearings, a friction disk at the lower end ol' said `shaft, a driven shaft extendinff longitudinally below said friction disk, a `riction pulley splined upon said driven shaft, a casingr in which said pulley is shiftably inclosed'and in which the driven shaft is journaled, transverse rock shafts journaletl in bearings in the vehicle frame and niovably supporting said casing froiniand toward the friction disk.

10. ln a motor vehicle driving mechanism, the combination with the vehicle frame and body, of an explosive engine carried upon the frame forward of the drivers seat and supported thereon with its main shaft in vertical position, fly Wheel on the lower end of the vmain shaft nda ted to form a friction disk, a casing vertical y movahlv supported from the frame below the friction disk, a driven shaft passing through said casing in the longitudinal direction of the frame and `vertically movable with the easing, a friction pulley splincd e upon the shaft and sbiftable ing connection with the casing for raisiinr and loweringl the same and a shiftingr roil longitudinally guided in the frame in the vertical plane of the driven shaft and having actuating connection with the friction pulley for shifting the same upon the drive shaft and a hand lever having actuating connection with the friction pulley. i

1 l n a motor vehicle drivingI` mechanism, the combination with the vehicle frame and rear axle, of an explosive engine mounted upon the forward end of the frame with its main shaft maintained in vertical position and with its tl)v wheel rotating in a horizontal plane at the lower end thereof, said fly wheel provided with a face forming a friction disk, a longitudinally dis )osed shaft below the main shaft having a. front portion carrying ashil'table friction pulley and a rear portion extending to the rear axle and having power transmitting connection therewith, the front and rear portions being flexibly connect-ed, and :teasing suspended from the vframe and vertically movable under control of the operator. said frame provided with bearings in which the front portion of the driven shaft is journaled and also forming an inc-losing housing for the flywheel and friction pulley.
